SHOT-SPREADING DEVICE FOR GUN-MUZZLES.

Specification of Letters Patent.

Patented May 29', 1917.

Application filed August so, 1915. Serial No. 117,649.

To all lrlwm it may eonnera lie it known that l. Janics E. \Ymuu'r, a citizen of the United States, residing at Bay il)'.ill the county of Bay and State of l\lir.higan. have invented certain new and useful lmprovenwnts in fihohfipreading Devices for (inn-Muzzles; and I do hereby deelare the following to be a full, clear, and eXart description'ot-pthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to guns and pertains more particularly to guns either of large or small ('aliher. adapted for firing a number oi projectiles simultaneously. The improvement is lnore particularly for use in light or heavy artillery guns,shot guns, riot guns, tl'elu'li guns and thelike.

'l"he object. ol the improvement is to pro videa muzzle ronstruetionfor guns, the muzzle being adapted to deflect the projectiles in such scatter lo any great extent in a vertical direction, but will spread widely in a'horizontal direction.

'lh'e muzzle (amstrm-tion, which eomprises my present improvement may be. combined Fig. 6 isa d either with the barrel of the gun to form an integral part thereof, or it can be made detachable from the barrel.-

A gun built in accordanee with my improvement, as for example, a 12 gage shot gun loaded with twelve BB buekshot, spreads the shot to inelude an area fourteen inches high by eight feet wide at a distance of thirty yards.

\Vith the above andcertainother objects in view, which will appear later in the'specifieation, niy invention comprises the devices described, and the equivalents thereof.

In the drawings, Figure 1 representsa showingmy improvement attached.

Figflfi is a side. view of alshot gun emboldymgiuy immovemelnt;

iagrammatie end yiew of the muzzle of av gun showiugthe manner in which shot of smaller size are discharged.

As is clearly shown in the drawings, the

improvement consists in providing the bar- 'a manner that they will not' rel of a gun with -a muzzle, which is flatted in a vertical direction and spread or widened in a horizontal direction.

1 represents the barrel of a cannon aml 3 is its flatted muzzle.

Referring to Figs. 1 andB,.the width 3 of the fiatted muzzle 2 is ,eonsiderably greater than the height 4 of the muzzle. opening. The muzzle preferably has flaring sides 5, a and a short parallel sided extremity (3, (i. In small arms, suclras shot guns, the height or the muzzle opening is preferably just sutli eient to permit the passage of a single pro-- jectile, as indicated diagrammatieally in Fig. 4.

The muzzle 2 may be made integral with the barrel, or it may be removably secured thereto. When the muzzle is made removable, as shown in Fig. 2, it may be attached to the barrel by any suitable means, as for example .by screw threads 7.

I do not, however, desire to confine myself to the use of any specific means for fastening the removalfle muzzle to the barrel.

While I have shown and described the im provement as appliedto a cannon, it may, as above noted, he applied to a shot gun or equivalent fire-arm, as at 2? in Fig. 5.

As has been previously stated, when my improvement is applied to small arms, suc

as shot s ams, the vertical height of the muzzle opening is preferably just sufiigient to permit a. single projectile to pass, thus allowing a. row of bullets to leave the muzzle simultaneously. The flaring sides 5, 5 per mit the shot to spread, while. the parallel sided walls 6, (3 prevent the shotsprea ding too far. l" he spread of the shot can thereby be made ,cofsu-it the effective range of the gun.

, In the case of a cannon the muzzle open? ing may be proportioned in the same We. .I

.llowever, projectiles of about three-eight is .100

inch or larger in size may be employed in the cannon and the muzzle opening is in 'r such case preferably so proportioned-that its cross sectional area will be almost equal to the Cl'()SS"S(3Ctl0l]t\l area. of'the bore of the-- gun, therebyslightly choking the muzzle and efleetirely utilizing the. propelling force of the explosive throughout the entire length of the barrel.

.VVhile I have shown and described the -iniprovement as embodying a'flatted muzzle of relativelyshortlength (see Fig. 2), .i tis obvious that any less or greater length of flattening can be adopted without departing from my invention.

Having thus described my inrcntiomxvhat I claim and desire to protect by Letters Patent is:

1. A gun barrel comprising a tube formed. with a bore, the muzzle end of said tube be ing fiatted to form a muzzle opening, the horizontal width of which is greater than its height, the height being sufficient to permit the passage of a single projectile, for the purposes set forth.

Q. A gun barrel comprising a tube formed with a bore, the muzzle end of said tube being flutted to form a muzzle opening, the

. cross sectional area of which is slightly less than the cross sectional area of the bore, the

horizontal width of said opening being greater than its height, the height being sufficient to permit the passage of a single projectile, for the purposes set forth.

3. A gun barrel comprising a tube formed with a bore, the discharge end of said tube being flatted to form a spreading muzzle,

said muzzle formed with outwardL flaring 2:;

sides, intermediate its ends, and --l)& llilll0lsides near its extremity. v

In testimony whereof, I affix ply srgnlituro in presence of two-witnesses.
